1 year ago Hi, I programmed a generic 16x16 Display from the shelf based on the logic of this project here for a Raspberry Pi Pico since the big Pi are too expensive and not easy to get.
I am new to this kind of GitHub work but want to share my experience.
I have to modify the original addressing to a WordClock compatible style, see below the addressing conversion for the correct order to work with the first part, an beside that I changed the order of the letters slightly, there is an svg file available for this layout.

There are a lot of different wiring possibilities to choose from in wiring.py. Only one is really documented, the Bends wiring, Are there drwaings for these alternative wirings?
Has somebody already written a section to make the workdclock run (more or less) centered on a 16 x 16 LED matrix panel?
thanks, Kas
